Currently, there are mainly three update paths built in parallel within the MCO. They separately take care of non-image updates, image updates, and updates for pools that have opted in to On Cluster Layering. As a new bootc update path will be added in with the introduction of this enhancement, MCO is looking for a better way to better manage these four update paths who manage different types of update but also shares a lot of things in common (e.g. check reconcilability). Interest and Proposals in refactoring the MCD functions and creating a unified update interface has been raised several times in previous discussions:

• Image-Based RHEL + OCP Journey
• Update Consolidation Effort
